  • Patent number: 9669240
    Abstract: A therapy system includes a therapy module to perform successive deposits of energy in a target zone. The therapy system further includes a control module configured to, prior to deposits of energy, produce an a priori estimate of the induced heating. A thermometry module is configured to measure temperature in a measurement field. The induced heating may be derived based on a tissue model from the settings of a therapy module. The therapy module includes a high-intensity focused ultrasound transmitter. A magnetic resonance examination system configured for thermometry is employed as the thermometry module.

  • Patent number: 8496587
    Abstract: A therapy system includes a therapy module, e.g., a high-intensity-focused ultrasound transmitter, to perform successive deposits of energy in a target zone. The successive deposits being separated by a cool down period. The therapy system further includes a thermometry module, e.g. by a magnetic resonance examination system, configured for thermometry to measure temperature in a measurement field. A control module regulates the cool down period in dependence of the measured off-focus maximum temperature during the energy deposit preceding the cool down period.

  • Patent number: 6671538
    Abstract: An interface system is provided for planning a surgical procedure for inserting an object into a patient along a surgical planning trajectory from an entry point on the patient to a target point within the patient. Using an imaging device, a first scan of the patient is performed to generate a first image volume data set of a first area of the patient. A first sectional image of the patient is displayed on a human-readable display device associated with the imaging device. The first sectional image is based on the first image volume data set. Using an operator interface device, a second planning image of the patient is defined by placing a plurality of graphical point symbols in the first sectional image of the patient displayed on the display device. The plurality of graphical point symbols define a second area of the patient to be subject of display as a second sectional image of the patient.
